Gold nanoparticles (AuNPs) have unique electronic and chemical properties and hence are used in many applications. However, their potential health risk(s) and interactions with cells are not fully known. Most previous studies have focused determining [...]
Zein, a protein abundant in corn, is capable of self-assembly and may form a variety of structural morphologies (Wang et al 2004, Wang et al 2008a). Zein micro-fibers (Figure 1.), films, and sponges (Figure 2) [...]

Our previous and on-going studies indicated that U87 cells cultured on chitosan film/membrane exhibited significantly slower growth and proliferation kinetics compared to U87 cells cultured in the absence of chitosan film/membrane. Chitosan exhibits anti-microbial activities [...]
A ferritin mutant protein, which can efficiently catch gold nanoparticles of various sizes and endow gold nanoparticles a new property to adsorb to Titanium/Titanium oxide surface, was reported.
It was determined that polyurethane polymers have the potential to be valuable biomaterials. Some major problems with this material involve its low biocompatibility and its inability to induce cellular adhesion and proliferation on its surface, [...]
The PEM coatings were applied on magnetic particles and the deposited films were examined by zeta-potential analysis and fluorescence microscope. Additionally, we utilized layer-by-layer deposition method to modify the surface of the micro-channel of the [...]
Certain insect viruses produce stable infectious microcrystals called polyhedra which function to protect the virus after the death of infected larvae. Polyhedra form within infected cells and contain numerous virus particles embedded in a crystalline [...]
Modeling studies have revealed that the pulse of nanosecond-duration should create smaller pores than the pulse of micro-millisecond duration. It can be expected, that similar differences should also exist between the pore populations created by [...]
The applications of carbon nanotubes (CNTs) have tremendous potentials for them as substrates of cell cultures, drug delivery systems, and medical implantable materials. We characterized the energy simulations of different CNT-composite materials with the use [...]
Electrospunned silk fibroin has been considered as scaffold for tissue engineering. Particularly, it has been used for bone regeneration with nano-hydroxyapatite (nHA). Though some papers showed successful results of bone regeneration in nHA and electrospunned [...]
Manufactured nanobiomaterials exploit the unusual properties of nanomaterials to develop new forms of intervention in biological systems. Nanobiotechnology is the field of science focused on the design, synthesis, characterization and application of nanomaterials and nanodevices [...]
